--- cleaned up, e.g. no longer older viewers

+-- The problem with widgets is that so far each version of acrobat
+-- has some rendering problem. I tried to keep up with this but
+-- it makes no sense to do so as one cannot rely on the viewer
+-- not changing. Especially Btn fields are tricky as their appearences
+-- need to be synchronized in the case of children but e.g. acrobat
+-- 10 does not retain the state and forces a check symbol. If you
+-- make a file in acrobat then it has MK entries that seem to overload
+-- the already present appearance streams (they're probably only meant for

-%D   {text}
-%D
-%D [TH] \type {\text} is a command to typeset more or less
-%D ordinary text inside of super- and sub|-|scripts. It has to
-%D do a full font switch to get the sides right, so it will be
-%D quite slow. \type {\text} kind of replaces \CONTEXT's \type
-%D {\mathstyle} command.
-
-%D [HH] This macro is now also moved to the core, but we
-%D keep it here as well for completeness.
-%D
-%D \starttyping
-%D \unexpanded\def\mathtext
-%D   {\mathortext\domathtext\hbox} % {\ifmmode\@EA\dotext\else\@EA\hbox\fi}

-%D   {\mathchoice
-%D      {\dodomathtext\displaystyle\textface        {#1}}%
-%D      {\dodomathtext\textstyle   \textface        {#1}}%
-%D      {\dodomathtext\textstyle   \scriptface      {#1}}%
-%D      {\dodomathtext\textstyle   \scriptscriptface{#1}}}
-%D

-%D  %{\hbox{\everymath{#1}\switchtobodyfont  [#2]#3}} % 15 sec
-%D   {\hbox{\everymath{#1}\setcurrentfontbody{#2}#3}} %  3 sec (no math)
-%D \stoptyping
-
-%D [HH] We use the following indirectness because \type {\text}
-%D is a natural candidate for user macros (actually, it is
-%D used in some modules).
-%D
-%D \starttyping
-%D \let\text\mathtext
-%D \stoptyping
-
-%D [HH] Actually, the font switch is not that slow when
-%D typefaces are used. If needed this macro can be sped up.

-%D \stopbuffer
-%D
-%D \typebuffer
-%D
-%D \getbuffer
-
-%D \macros
-%D  {mathhexbox}
-%D
-%D [TH] \type {\mathhexbox} is also user||level (already
-%D defined in Plain \TEX). It allows to get a math character
-%D inserted as if it was a text character.
-
-\gdef\mathhexbox#1#2#3{\mathtext{$\mathsurround\zeropoint\mathchar"#1#2#3$}}

-%D \macros
-%D   {boxed}

-
-\def\boxed
-  {\ifmmode\expandafter\mframed\else\expandafter\framed\fi}
-
-%D \macros
-%D   {cfrac}
-%D
-%D [HH] Now let us see what this one does:
-%D
-%D \startbuffer
-%D $\cfrac{12}{3} \cfrac[l]{12}{3} \cfrac[c]{12}{3} \cfrac[r]{12}{3}$
-%D $\cfrac{1}{23} \cfrac[l]{1}{23} \cfrac[c]{1}{23} \cfrac[r]{1}{23}$

-      {\strut\ifx r#1\hfill\fi#2\ifx l#1\hfill\fi}%
-      {#3}}%
-    \kern-\nulldelimiterspace}
-
-%D [HH] The next alternative is nicer:
-
-\def\simplecfrac     {\docfrac[cc]}
-\def\complexcfrac[#1]{\docfrac[#1cc]}
-
-\def\docfrac[#1#2#3]#4#5%

-
-%D [HH] Now we can align every combination we want:

-%D \startbuffer
-%D $\cfrac{12}{3} \cfrac[l]{12}{3} \cfrac[c]{12}{3} \cfrac[r]{12}{3}$
-%D $\cfrac{1}{23} \cfrac[l]{1}{23} \cfrac[c]{1}{23} \cfrac[r]{1}{23}$
-%D $\cfrac[cl]{12}{3} \cfrac[cc]{12}{3} \cfrac[cr]{12}{3}$
-%D $\cfrac[lc]{1}{23} \cfrac[cc]{1}{23} \cfrac[rc]{1}{23}$

-
-%D \macros
-%D   {splitfrac, splitdfrac}
-%D
-%D Occasionally one needs to typeset multi||line fractions.
-%D These commands use \tex{genfrac} to create such fractions.
-%D
-%D \startbuffer
-%D \startformula
-%D      a=\frac{

+%D   {overlaybutton}
+%D
+%D For converience we provide:
+%D
+%D \starttyping
+%D \overlaybutton[reference]
+%D \stoptyping
+%D
+%D This command can be used to define overlays an/or can be
+%D used in the whatevertext areas, like:
+%D
+%D \starttyping
+%D \defineoverlay[PrevPage][\overlaybutton{PrevPage}]
+%D \setupbackgrounds[page][background=PrevPage]
+%D \setuptexttexts[\overlaybutton{NextPage}]
+%D \stoptyping
+%D
+%D For practical reasons, this macro accepts square brackets
+%D as well as braces.

+%D In \MKII\ we had to cheat a bit with setups in order not to run
+%D out of memory with thousands of fields, which we happen to need at
+%D that time. In \MKIV\ we can store some data at the \LUA\ end and
+%D use a somewhat slower but quite okay inheritance mechanism. For
+%D this reason we now have split definitions, although the old method
+%D is still somewhat supported. The clone and copy commands are
+%D somewhat obsolete for several reasons: we can now use inheritance
+%D and autocloning has been supported for a while. In most cases
+%D cloning (especially with check boxes) the acrobat browser is not
+%D stable enough with respect to appearance handling.
+%D
+%D A fieldcategory is nothing more than a collection of settings.
+%D
+%D \starttyping
+%D \definefieldcategory
+%D   [all-email]
+%D   [height=1cm,
+%D    width=14cm,
+%D    style=sstf]
+%D \stoptyping
+%D
+%D A definition can refer to this category:
+%D
+%D \starttyping
+%D \definefieldbody [email] [type=line,category=all-email,default=pragma@wxs.nl]
+%D \stoptyping
+%D
+%D A copy of a field is made as follows:
+%D
+%D \starttyping
+%D \definefieldbody [xmail] [email]
+%D \stoptyping
+%D
+%D You can also be more specific:
+%D
+%D \starttyping
+%D \definefieldbody[buttona][type=check,values={one,two}]
+%D \definefieldbody[buttonb][type=check,values={three,four}]
+%D \definefieldbody[buttonc][buttona][values={three,four}]
+%D \stoptyping
+%D
+%D Actually typesetting a field happens this way:
+%D
+%D \starttyping
+%D \fieldbody [Email]
+%D \fieldbody [Email] [width=6cm]
+%D \fieldbody [eMAIL]
+%D \fieldbody [eMAIL] [width=7cm]
+%D
+%D \fieldbody [buttona]
+%D \fieldbody [buttona]
+%D \fieldbody [buttonb]
+%D \fieldbody [buttonb]
+%D \fieldbody [buttonc]
+%D \fieldbody [buttonc]
+%D \stoptyping
+%D
+%D So, you can call up a field many times and quite some parameters
+%D can be set.
+%D
+%D Because there are persistent problems with acrobat rendering
+%D associated appearance streams (some messy /MK interferende) we
+%D also support native (built-in dingbat) symbols: check, circle,
+%D cross, diamond, square and star.
+%D
+%D \starttyping
+%D \definefield[test1][check]
+%D \definefield[test2][check]
+%D
+%D \fieldbody[test1][width=1em,height=\strutht,depth=\strutdp,symbol=check]
+%D \fieldbody[test1][width=1em,height=\strutht,depth=\strutdp,symbol=circle]
+%D \fieldbody[test2][width=1em,height=\strutht,depth=\strutdp,symbol=square]
+%D \stoptyping
+%D
+%D When submitting a form, we need to tell the driver module
+%D that we want \FDF\ or \HTML.

+%D \CONTEXT\ had tooltips right from the moment that it
+%D supported fields. Due to the at that moment somewhat
+%D limited \PDF\ specification, they were implemented
+%D using \JAVASCRIPT, but nowadays more kind of actions
+%D are supported, so we can do without. The \MKIV\ version
+%D also supports definition of tooltips and configuration.

+%D As this functionality was in the core and as I don't know
+%D how often it is used, we'll keep it around. However, it is
+%D upgraded and usage has changed a bit. We also use some
+%D \LUA\ magic in order to avoid multiple passes.
+
+\registerctxluafile{scrn-hlp}{1.001}
+
+%D Using help boils down to plugging the placement macro
+%D someplace visible, like:
+%D
+%D \starttyping
+%D \setuptexttexts[\centerbox{\placehelp}]
+%D \stoptyping
+%D
+%D When this is done, the following should work out okay:
+%D
+%D \starttyping
+%D test \helptext{word}{tip top 1 is somewhat longer} test
+%D test \helptext{word}{tip top 2} test
+%D
+%D \starthelptext[oeps]
+%D \input tufte
+%D \stophelptext
+%D
+%D test test \showhelp{some help}[oeps] test
+%D test test \button[location=depth]{\helpsignal{oeps}OEPS}[oeps] test
+%D
+%D test test \button[location=depth]{next}[page(2)] test
+%D
+%D \page
+%D
+%D test \helptext{word}{tip top one} test
+%D test \helptext{word}{tip top two} test
+%D \stoptyping
+%D
+%D Currently you need to use the signal in custom macros but
+%D that might change at some point.

+%D As long as there a natural feeling of what can be considered
+%D hyper active or not, we have to tell users where they can
+%D possibly click. We've already seen a few macros that deal
+%D with this visualization, something we definitely do not let
+%D up to the viewer. One way of telling is using a distinctive
+%D typeface, another way is using color.
+%D
+%D There are two colors involved: one for normal hyperlinks,
+%D and one for those that point to the currentpage, the
+%D contrast color.
+
+\definecolor [interactioncolor]         [r=0,  g=.6, b=0]
+\definecolor [interactioncontrastcolor] [r=.8, g=0,  b=0]
+
+%D The next few macros are responsible for highlighting hyper
+%D links. The first one, \type{\showlocation}, is used in those
+%D situations where the typeface is handled by the calling
+%D macro.
+
+%D When we're dealing with pure page references, contrast
+%D colors are used when we are already at the page mentioned.

-%D with this visualization, something we definitely do not let
-%D up to the viewer. One way of telling is using a distinctive
-%D typeface, another way is using color.
-%D
-%D There are two colors involved: one for normal hyperlinks,

-%D The next few macros are responsible for highlighting hyper
